Rated output within it ranges from 98 to 130 hp; the 8100 sits in the upper part of that range with 120 hp. Its immediate neighbours are the 8000 below it with 98 hp and the 8200 above it with 130 hp. Unladen weight within it ranges from 4,560 to 4,700 kg; here the 8100 sits in the lower part of that range with 4,600 kg. 414 Valmet models across 21 series are on record.

Valmet Mega range: collective page of Finnish tractors 8000 to 8200 from Suolahti, six-cylinder diesels up to 7,365 cm³, 72 to 96 kW (120 to 130 hp), 1990s

The Mega range from Valmet, dating from the 1990s and comprising the models 8000, 8100 and 8200, formed the top power segment of Finnish tractor production in Suolahti; the model numbers rank the three versions by power class. As the brand's top six-cylinder models, they stood clearly apart from Valmet's smaller three- and four-cylinder ranges and marked the upper end of the line-up at the time.

The register lists 3 versions with 72.1 to 95.6 kW (120 to 130 hp) from six-cylinder diesel engines of 6,593 to 7,365 cm³, unladen weights of 4,560 to 4,700 kg, lengths of 4,740 to 4,745 mm, widths of 2,170 to 2,200 mm and heights of 2,720 to 2,760 mm; torque ranges from 366 to 490 Nm at a rated speed of 2,225 rpm.

As the brand's most powerful range, the Mega handled heavy field work on large Nordic farms, such as deep ploughing and driving large implements, competing with the top six-cylinder models from Volvo BM/Valtra, Case IH and John Deere.

When buying used, condition of the six-cylinder diesel including turbocharger and cooling, the gearbox and hydraulics under full load, and the lift and PTO all matter; spare parts are available through today's Valtra network and independent farm-machinery dealers. The electrical system on these older six-cylinder models is also worth a close look.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.
Compare the data plate and chassis number with the papers.
Check the weights in the papers against the figures here — attachments change them.
Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
Shift the gearbox cold and warm — jumps only show up at temperature.
Load the hydraulics and watch for sag.
Ask about parts availability for this build year — the running costs hang on it.
